In graining wood with a graining-tool it has heretofore been customary to take a graining pigment varying in color with'the different kind'of wood to be represented, this pigment being. ina dry form and when used being di- .luted with vinegar or stale beer or some similar reducer. his has always been incon- The beer or vinegar has a sour unpleasant odor, is liable to ferment, the dilution'must be made at the time of use, and the amount of dilution varies the color, with the result that frequently various parts of. the same grained floor present a diiferent ap p'earance. Grainer in the form of a paste thinned: with drier and turpentine or benzene has been used; but it is not adapted for applicationby a graining-tool and requires considerable skill in its use.

I have dev'ised'a graining compound which. may be kept in stock ready mixed for use and may be applied by a'graining-tool without reis. hereinafter more quiring any special skill on the part of the Furthermore, I havedevised a sys user. tem of using it wherebythe same graining compound may be em loyed to represent a1 sorts of woods. This .accomplish by applyin a'colored translucent varnish to the lightco ored graining compound on' a 'still lighter ground. l

The method-of ap lyin the composition iiilly described and .the

essential characteristics set out in the claims. I make the pigment of my graining compound of substantially equal portions of raw sienna and whiting. These are mixed to:

.gether and grounded in water sufficient to make athin paste. This 'paste is then diluted with alcohol to the proper consistency for use. The composition itself is covered in my divisional application, Serial No. 333,183,

filed September 4, 1906.

'In applying the grainer I first apply a ing in applying a 7 ground coat of'lightstraw color. After this is dry the graining compound is applied. This is a light-yellow color and when dry is hardly perceptible on the light ground, presentin the a earance sim l of streaks 8 EP P Y thereon. Wit a colored transparent varnish applied to it, however, it-gives a beautiful natural grain to the wood. The tint ofthisvarnish depends on the wood it is in tended to imitate-yellow for oak,brown for walnut,-redfor cherry, &c. In each case the same graining compound may be used.

One of the advantages .of. my system is that there need be-no special skill on the part of the user, as with ordinary graining. There is no mixing or thinning of the materials. It is simply necessary to apply them with brushes and a graining-tool.

The alcohol in the compound not only forms a drier, but prevents creeping, so that the graining pigment retains its form when it dries. This pigment does not adhere like paint, but is retained in place by the varnish over it.

Icla1m 1. The process of producing surfaces in imitation of graining, consisting in applyin to the surface a graining compound carrie by a volatile vehicle, allowing such vehicle to evaporate and applying. over. the grainingcompound a colored varnish.

":2. The process of producing surfaces in imitation of graim'ng, consisting in applying aground coat,- applying over this a graining compound carried a volatile vehicle,- allowing such vehicle to'evap'orate, and ap lying over the grainin'g compound a varnish to bind the graining compound.
